KNOT-TYI NG APPARATUS.

SPECIFICATION formling` part'of Letters Patent No. 280,921, dated July. 10, 1883.

Application filed January 29,1883. (No model.)

lb @ZZ whom t my con/cern:

Be it known that I, Rim/ron C. Fav, of Hopedale, `county of Vorcester, State of Massachusetts, have invented an Improvement in This invention has for its object the produc-V tion of Ya device bywhich to tie knots-in threads or yarns and leave but a short piece of the same beyond the hard knot, my apparatusbeing applicable for use in warping, spooling, and similar machines.

My improved apparatus is composed of a standard having its-end forked and pointed, and preferably held together by an adjusting device,herein shown as a screw, by which the pronged parts may be adapted to operate properly with threads of different sizes.

'Figurelrepresents in side elevation a knottying apparatus embodying myinvention Fig. 2, a front elevation thereof; and Figs. 3 to 6inelusive, top views o f the knot-tying apparatus, shown in connection with two threads to be tied into a hard knot,the positions of the said threads in the different figures showing progressively the formation 'of a knot.

The standard c, fixed upon a beam or other suitable base, b, by screws c, has its upper end 1 forked or made to present yielding arms d e,

t Figs. 2te 6. The arms de, at their upper ends,

are held `more or less closely together, accordf ing to the size or diameter of the yarn or thread to be. tied, by means of the adjusting device j', (shown as a serew,) their Contact or position with relation to each other/being closer as the yarn or thread 5 6 i's-ner.

f When a hard knot is to be tied in two threads,

5 and 6,they will be brought together and held will form a loop of the shape shown in Fig. 3 y about the end of the forefinger of the'left hand, and will then place the said loop, while yet held by the iinger, over the looping-points 2 3 inthe position Fig. 3, and will, with the right hand,

draw the said threads, near their ends, down into the beveled space 4,betwcen the points, as

in Fig. 3, the threads, near their ends, crossing over the looped part of the thread back of itsA ends. the operator will continue with the right hand to draw upon the ends of the threads and draw the same down into the space 4 until, by their wedging into the said space and by reason of the strain thereon bythe operator, the said threads terminate close tothe rear side of the 7o looping-points. Thefree ends ofthe two threads being held as in Fig. 4r, the operator, bytheleft hand, will pull outward the threads 5 6, to draw them in the direction of the arrows 71., to take up the loop in the said threads, and in so do- 7 5 ing the said loop will be gradually contracted about the looping-points, as in Fig. 5,and then, by a slight upward movement of the left hand, the contracted loop will be drawn up or made to further contract and pass over the top ofthe So points, forming a hard knot, as at m, Fig. G, very close to the evened ends ofthe said threads.

' The arms and looping-points will be so set that the threads to be tied may be drawn down and be wedged into the space between them with sufficient force to be held `firmly clamped between the said arms after the projecting uneven ends of the said threads have been broken foff, as stated. The screw f may be turned to make the space between the said arms, at the 9o bottom of theinclines 1i, just wide enough to ren ceive and clamp and hold the particular threads being used.

I do not broadly claim a knot-tying apparatus having a rigid arm and a yielding arm 9 5 and cutter, down between which the thread or yarn is drawn and cut off, and then,a loop having been formed, is-.drawn up and off a prong on one of the said parts.

In this apparatus I have dispensed with a roo Vith the threads placed as in Fig. 3, 6o

separate or independent cutting-edge by which to sever the threads, and by means of the adjusting` device I havebeen enabled to adapt the apparatus to threads of varying,` sizes or diameters. Y v

I claimf l. The knot-tying apparatus herein described, it being composed of the forked standard having arms d c and looping-points beveled to form a space, 4, down into which the threads may be passed as they are drawn between the l points and arms7 to be held while the knot is,

being tied, substantially as described.

2. rlhe standard a, forked at its upper end to form yielding arms d e, and shaped to form looping-points,with a space between them for vscribing witnesses.

v the reception of the threads to be held and tied,

combined with an vadjusting device to place and keep the said arms at the proper di tance apart, substantially as described. f

3. l A knot-tying apparatus combined with an adjusting screw or device to adapt the "knottying apparatus for use with threads or yarn of differentsizes, substantially as described.

In testimony whereof I have signed my name4 25 to this speciication in the presence of two sub- RiMMoN c. FAYn Witnesses:
